MALLET.

SPECIFICATION forming part of Letters Patent No. 460,115, dated September 29, 1.891. Application tiled September 4, 1890. Serial No. 363,952. (No model.)

To ctZZ'w/wm t may concern.-

Be it known that I, GEORGE A. COLTON, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Mallets, of which the following is a specification, reference being' had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in mallets of that class wherein the faces are secured in position by means of interiorlythreaded rings; and it has for its objects, among others, to provide an improved device of this character wherein the faces or face shall have at all times a iirm bearing against the head of the mallet. It has for a further object to provide for the adjusting of the face as the same wears away. I also propose to use in connection therewith an improved face.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in whicl1- Figure l is a side elevation of my improved mallet with portions broken away andl parts in section, and Fig. 2 is a central longitudinal section through one of the securing-rings. Fig. 3 is a sectional view taken on the line cc f1: of Fig. l.

Referring now to the details of the drawings by letter, A designates the head, of any suitable material, and B the handle. The head is formed at either or both ends with a screw-threaded reduced portion c., forming shoulder b, as seen in Fig. l.

C is aband or ringinternallyscrew-threaded and preferably provided with a iian ge or flanges c, which serve to aid in the adjustment of the bands or rings, and which may be milled or roughened, if desired. The band may be provided with right and left screw-threads, as shown in Fig. 2, or the threads may be all of one kind, either right or left. For some classes of work-such, for instance, as in copper working, where there is a circular drawingstroke-I prefer the right and left threads,

as such construction prevents drawing out of the face by such stroke.

D are the faces, which are exterior-1y threaded to engage the threads ofthe rings or bands. They may be formed of any suitable material such as wood, leather, or rawhide-in layers or sections or wound in a roll. Heretofore in rolling there has been a soft spot or hole in the center where the start is made. At the right in Fig. l I have shown a face of wound leather or rawhide or similar material provided with a central core CZ, of any suitable material, as metal, which greatly improves the same and renders it much more durable. I may sometimes employ a face formed of fiber formed by rolling the liber, so asI to bring' the shock on the end of the grain, making it much more durable and less liable to split or chip than Where the grain is arranged at right angles thereto. Such a face would be substantially like the one shown at the right in Fig. l. It might or might not have a core. In practice the face is screwed into the band or ring a sufficient distance to allow it to project more or less, according to the character of the work for which it is to be used. flhe band is then screwed onto the threaded portion of the head until the adjacent faces of the face and head come in contact, as seen in Fig. l, when the mallet is ready for use. As the face becomes worn it may be adjusted outwardly and the band or ring screwed up enough to compensate for the wear, so as to bring the face and head always in contact, and when thus in contact the face cannot be moved in the band until said band is loosened sufficiently to separate the face and head. As a circular drawing stroke of the mallet might tend to turn the face so as to loosen it, I provide against such by the employment of the right and left threads, as seen in Fig. 2. The shoulders h limit the inward movement of the bands or rings.

By the term double-threaded, when used in connection with the band, I mean a band having threads upon its inner face at both ends, whether they be right and left threads or not.

l. A mallet having a head with 'screwthreaded portion, combined with a band or IDO ring having double interiorly-threaded portion to engage the threaded portion of the head, and a face also threaded to engage the threads of the band or ring, with the adjacent faces of the head and face in Contact with each other when adjusted, substantially as specified.

2. Alrnallet consisting of ahead, an adjustable band or ring having double-threaded interior surface, and a face adjustable in the band or ring, with its face always in contact with the head when adjusted, substantially as specified.

3. A mallet consisting of a suitable head and handle, the head having screw-threaded portion, aband provided internally with right and left screw-threads, and an adjustable face held in said band `or ring, the band or ring being adjustable on the screw-threaded portion of the head and the adjacent faces of the head and face designed to be always in Contact lwhen adjusted, substantially as specified.

4. An improved face for mallets, composed of a central rigid core wound with a fibrous covering, the axis thereof being at right angles to the acting portion of Jthe face, as set forth.

5. An improved face for mallefs, composed of a central rigid core Wound with a fibrous covering and eXteriorly threaded, as set forth.

In testimony whereof I afiiX my signature in presence of two witnesses.

GEORGE A. COLTON.
